Abstract (en)
[origin: EP0614622A1] Pressure-compensating pads such as seats or cushions used in wheelchairs, can be filled with a flowable, pressure-compensating composition comprising a major portion of silicone fluid, a minor portion of amide thickener which is essentially insoluble in said silicone fluid and microballoons. The resulting compositions are particularly characterized by their ability to flow in response to a continuously applied pressure, yet to maintain their shape and position in the absence of applied pressure, and are further characterized by stable viscosity at temperatures generally associated with the presence of the human body and excellent fire retardant properties. The composition may also contain flame-retardant.
